Abstract: In a process for the deposition fo silicon carbide coatings a gaseous mixture consisting, by volume, of not more than 40% of one or more organo-silicon compounds and not less than 60% of a gaseous diluent is passed at a temperature of 1450-1600  DEG C., under a pressure of 0.1 - 100 atmospheres gauge and at a velocity of 0.01 - 500 cm./sec., calculated at 20  DEG C., in contact with the substrate(s) to be coated.  Doped coatings may be deposited by using an organo-silicon compound which contains an element of Group II - VII of the Periodic Table bound to silicon and/or carbon, or by adding such an element in elementary or combined state to the gaseous mixture.  Specified organo-silicon compounds are dimethyl and tetramethyl silane, methyl trichloro- and dimethyl dichloro-silane, and phenyltrichlorosilane. Specified diluents are hydrogen, nitrogen, carbon monoxide and rare gases.  Specified substrates are carbon, graphite, silicon, boron, tantalum, titanium, tungsten, molybdenum, silicon carbide, boron carbide and titanium carbide.  If desired, the coating may be built up in different layers by variation of the composition of the gas mixture. After coating, the substrate may be removed to produce a pure silicon carbide article.

Abstract: 717,931. Valve amplifying circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 13, 1953 [Nov. 7, 1951], No. 26062/51. Class 40 (6) In a cathode-follower circuit auxiliary feedback is provided to counteract changes in anode current and anode-cathode voltage with change in input level. Compensation may also be provided for changes in the supply potentials. The anode-cathode potential of the cathode-follower V1 is maintained constant by means of an auxiliary cathode-follower V2 connected in series with the anode of the valve V1, the grid of the valve V2 being maintained at a value which is fixed relative to the output potential by means of a constant-potential discharge tube V3. The anode current is maintained constant by an auxiliary valve V4 connected in series with the cathode of the valve V2: any change in the anode current develops a potential change across resistance R which is transferred, via resistance S and a valve V5 acting as a constant-current device, to the grid of valve V4: so as to oppose the original change in current. The valve V4 is provided with a cathode bias resistance, the bias being maintained constant by an auxiliary valve V6. A resistances r is provided. in the cathode-circuit of the valve V1 so that the input and output D.C. levels may be made the same. To compensate for changes in supply potential the grid of the valve V6 is connected to an auxiliary network comprising valves V7, 8 and resistances R<SP>1</SP>, S<SP>1</SP>, corresponding to the network V2, 5 and R, S. 'The effect of change of heater potential in the valve V1 is compensated by means of valve V9. Shunting condensers C1, 2, 3 improve the response to rapid changes of input level. The grid potential of the va!ves V5, 7 may also be stabilized by means of a constant-potential dischange tube, Fig. 6 (not shown); 'a condenser may also be provided between the cathode of the valve V5 and ground, Fig 7 (not shown), in order to improve the stability of the arrangement.
